Spanner ratchet wrench



April 1945- G. VAN GENDEREN SPANNER RATCHET WRENCH Filed March 6, 1945' lllflllllllll 7' TORNE X Patented Apr. 10, 1945 UNITED STATES PATENT OFFICE SPANNER RATCHET WRENCH Gerrit Van Genderen, Royal Oak, Mich. Application March s, 1943, Serial No. 478,176 1 Claim. (Cl. 811 -90) This invention relates to spanner wrenches.

It is particularly directed to a ratchet type spanner wrench. Y

An object of this invention is to provide a wrench of the character described which will ratchet a half turn to greatly facilitate removing of plugs and for the like purposes.

A further object of this invention is to provide a strong, durable and rugged wrench of the characterdescribed which shall be easy to manipulate, relatively inexpensive to manufacture and yet practical and efficient to a high degree in use.

Other objects of this invention will in part be obvious and inpart hereinafter pointed out.

The invention accordingly consists in the combination of steps, features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claim,

In the accompanying drawing, in which is shown one of the various possible illustrative embodiments of this invention,

Fig. 1 is a side elevational view of a wrench embodying the invention;

Fig. 2 is a bottom plan view thereof;

Fig. 3 is a view similar to Fig. l but illustrating a modified construction; and Fig. 4 is a bottom plan view of th structure shown in Fig. 3. 7

Referring now in detail to the drawing, l designates a spanner wrench of the pin type embodying the invention. The wrench l0 comprises a jaw H, said jaw ll consists of a rod l2 of rectangular cross section. Attached to the rear end of rod l2 are a pair of parallel similar plates l3 extending downwardly therefrom and forming a channel 14 therebetween. The plates I3 may be attached to rod l2 by means of a plurality of transverse pins 15 press-fitted through aligned openings in the plates and rod. The plates I3 are formed with slots l1 and the upper edges of the slotsare formed with ratchet teeth H3. The teeth I8 are disposed below the rod l2 as shown on the drawing. Pivoted to jaw H is a jaw 20. The same comprise a rod likewise of rectangular cross section and preferably of the same stock as rod [2} The rear end of jaw 20 fits within the channel l4 between the plates l3.

Fixed to the rear end thereof is a transverse pin 2! extending through slots IT. The pin 2| extends beyond rod 20 as shown in the drawing. The pin 2| is adapted to engage the ratchet teeth I8 so as to lock the jaw 20 against sliding movement relative to jaw H in a, rearward direction while permitting the pinto slide forwardly beneath the teeth l8. Attached to the front end of rod I2 is a transverse pin projecting from opposite sidesof said rod. Attached to the front end of rod 20 is a transverse pin 26 likewise extending to opposit sides of said jaw. The pins 25 and 26 are adapted to engage in openings in a plug. It will be noted that jaw 20 may move angularly relative to jaw H so as to fit different size plugs or for different spacing of holes or openings to be engaged by the pins 25 and 26.

The operation of the device will be understood. The pins 25 and 26 are first engaged in the opening of the article to be turned. Member III is then moved in a counter-clockwise direction, causing pin 2| to move forwardly to the left end of slots 11. The device is then turned in a clockwise direction causing the pin 2| to engage one of the ratchet teeth thus fixing the jaws so that the wrench will turn the article engaged by the pins 25, 26. In Figs. 3 and 4 there is shown a wrench 13a embodying the invention and illustrating a modified construction. The wrench Illa comprises a rod 30 to the rear end of which there is attached a pair of plates 3| similar to the plates l3 by means of pins lBa. The plates 3| likewise have slot 32, the upper jaws of which are formed with ratchet teeth 33. Extending between the plates 3| is the rear end of rod 35 which has a pin 36 projecting into the slots 32. The forward end of rod 30 is formed with a slot 31' and the forward end of rod 35 is formed with a similar slot. Pivoted to the forward ends of rods 30, 35 is a hook shaped member 38. Said hook shaped member 38 has ears 39 and 40, received within the slots at the forward ends of rods 30, 35. The ears 39 and 40 are pivoted to said rods by means of pins 42 and 43, and shown in the drawing. The hook 38 has a. projection 42 to engage in an opening.

The operation of member Ilia is similar to the operation of member In.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanydrawing is to be interpreted as illustrative and not in a limiting sense.

edge of the plate defining each slot having a series of ratchet teeth, a second elongated rod having one of its ends within said channel, a transverse pin projecting through the end of said last mentioned rod within said channel for coaction with said ratchet teeth, and a transverse pin secured to the opposite free end of each of said rods.
